D1 is shown), and the first elastic member 34 is compressed by an external force in the direction toward the front end portion 311. In addition, since the protruding portion 321 of the rotating member 32 urges the cam member 33 to be displaced toward the front end portion 311, the second elastic member 35 and the third elastic member 36 are also stretched, that is, the first elastic member 34 is The second and third elastic members 35, 36 are subjected to the tensile force when subjected to the compressive force. In this state, the user can place the electronic device 1 on a desktop 2 (as shown in FIG. 4C), wherein the display module 10 of the electronic device 1 can be supported by the supporting force (reaction force) of the desktop 2 and The frame 20 is maintained in the aforementioned open state, thereby providing a good viewing angle for the user to view the screen on the display module 10.

It should be noted that when the user wants to retract the electronic device 1 as shown in FIG. 4C and return to the closed state as shown in FIG. 3A, the electronic device 1 can be directly turned up by hand (as shown in FIG. 4C). The display device 10 and the frame 20 of the electronic device 1 are no longer subjected to the supporting force of the desktop 2, and the pivoting mechanism 30 is compressed. The first elastic member 34 and the stretched second and third elastic members 35, 36 automatically return the electronic device 1 to the closed state as shown in FIG. 3A by its elastic restoring force (eg, 4C). The direction in the figure is shown by R1). In this way, the user can conveniently switch the posture of the electronic device 1 through a simple operation.

Fig. 5 is a view showing an electronic device 1' of another embodiment of the present creation. As shown in FIG. 5, the electronic device 1' in this embodiment is, for example, a notebook computer, and the main difference from the electronic device 1 is that an input module 40 is added.
